Properties of non newtonian fluids

WebNon-Newtonian behavior of fluids can be caused by several factors, all of them related to structural reorganization of the fluid molecules due to flow. In polymer melts and solutions, it is the alignment of the highly … WebMany non-Newtonian fluids are actually slurries of suspended particles in a liquid. Paint, clay slips, and wet sand are examples of fluids that exhibit this strange behavior. Figure 3-12 is a graph of shear stress vs. shear rate. In the case of a rotational viscosimeter, it would be rpm vs. torque. Newtonian fluids show a straight

A non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity, that is, it has variable viscosity dependent on stress. In non-Newtonian fluids, viscosity can change when under force to either more liquid or more solid. Ketchup, for example, becomes runnier when shaken and is thus a non-Newtonian fluid. Many salt solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as custard, toothpaste, starch suspensions, corn s… WebApr 14, 2024 · Before the intersection point, the flow rate of non-Newtonian fluid is greater than that of Newtonian fluid (n = 1).
